This seems to be fixed by installing xorg-x11-drv-intel 2.99.917-2.fc22 from Rawhide on Fedora 21. xorg-x11-drv-intel 2.99.916-3.20141117.fc21 shows the bug.
After installing the rawhide version of this driver switching vts is much less painful.
ping? I can issue an update for you and rebuild the Rawhide driver for F21 if you do not have the time.

Are you one of its maintainers? No, not a maintainer. Just thought you might want people to test it and sound off on whether it worked for them or not.

I can prepare an RPM if you are interested. A colleague of mine is using it already because his system would be mostly unusable otherwise.
Since installing the rawhide version of this driver I have not had a single black screen hang when switching VTs, and the switch from one user screen to another is nearly instantaneous. Not sure what I could do, but I'd be willing to help.

This message is a reminder that Fedora 21 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 21. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '21'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 21 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 21 changed to end-of-life (EOL) status on 2015-12-01. Fedora 21 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
